Arsene Wenger's side won 2-0 at the Allianz Arena, but agonisingly dropped out of the UEFA Champions League on the away goals rule.
The Gunners bounced back from that disappointment with a 2-0 victory at Swansea last time to sit fifth in the Premier League, four points behind arch-rivals Tottenham with a game in hand.
Next up, Arsenal face relegation strugglers Reading at the Emirates on Saturday, and Rosicky is relishing a return to domestic action after the international break.
"Ideally, I don't think we would have had a break after the last two results," Rosicky told Arsenal's official website.
"The game in Munich could be the equivalent of last season's Tottenham game - the stepping stone or turning point. Three days later, at Swansea, we put in another very good performance.
"Now we need to pick up that momentum again. It's a very interesting period for us now, fighting for a place in the Champions League."
Arsenal finished strongly to claim a place in the Champions League last season and Rosicky is looking for more of the same.
"That's what I expect to happen - that we will be there again," he said.
"Of course it will be a tough task, but our advantage is that we had the same experience last year. We know it's very possible but we have to be consistent.
"Inconsistency has bothered us at times this season, but I believe we will produce a strong finish and we will make it."
